What are you using to load the authentication server?

evan-goode commented 6 months ago

Thanks for the bug report.

anthonywww commented 6 months ago

Hi,

I tested this with all combinations of enforce-secure-profile and SignPublicKeys both being true, both false, first true, second false, etc. they all show the same error. I also refreshed my session token each time before testing again (re-launching) just to make sure via HMCL's "refresh" button.

Thanks for the details, I can reproduce this with HMCL but not PollyMC. Gonna try to debug.

evan-goode commented 6 months ago

@anthonywww would you mind trying the fix in https://github.com/unmojang/drasl/pull/42?

anthonywww commented 6 months ago

Pulled branch https://github.com/unmojang/drasl/tree/fix-hmcl and it works on 1.20.2. Thanks!

evan-goode commented 6 months ago

Great, fixed in v1.0.2.
